The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0022] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present utility model belongs.

[0023] Referring to Figures 1-4 , a tightening tool for the end sleeve of a bicycle cable includes a housing 1. The inner bottom wall of the housing 1 is fixedly connected with a first partition 2. A servo motor 3 is fixedly installed on the inner bottom wall of the housing 1. The output shaft of the servo motor 3 is fixedly connected with a lead screw 4 through a coupling. One end of the lead screw 4 penetrates and extends to the side surface of the first partition 2. The inner bottom wall of the housing 1 is fixedly connected with a mounting block 5 through a connecting block. The inner wall of the mounting block 5 is fixedly installed with the outer surface of one end of the lead screw 4 through a bearing. A moving block 6 is threadedly sleeved on the outer surface of the lead screw 4. The inner wall of the moving block 6 is movably sleeved with guide rods 7 distributed symmetrically. When the moving block 6 moves, the guide rods 7 guide and limit the moving block 6;

[0024] One end of each of the two guide rods 7 is fixedly connected to one side surface of the first partition plate 2, and the other end of each of the two guide rods 7 is fixedly connected to one side surface of the mounting block 5. The servo motor 3 drives the lead screw 4 to rotate. With the cooperation of the guide rods 7, the rotation of the lead screw 4 drives the moving block 6 to move.

[0025] Furthermore, the upper surface and the lower surface of the moving block 6 are hinged with symmetrically distributed first connecting rods 8 through pins, and the upper surface of the first connecting rod 8 is hinged with a second connecting rod 9 through a pin.

[0026] Furthermore, the inner walls of the two second connecting rods 9 are both movably sleeved with cylindrical rods 10, and one end of each of the two cylindrical rods 10 is fixedly connected to the inner bottom wall of the housing 1.

[0027] Furthermore, the other end of each of the two cylindrical rods 10 is fixedly connected to the inner top wall of the housing 1. The opposite surfaces of the two second connecting rods 9 are respectively hinged with a tightening clamp 11 through pins. The upper surface and the lower surface of the tightening clamp 11 are respectively hinged with symmetrically distributed third connecting rods 12 through pins. The movement of the moving block 6 drives the tightening clamp 11 to move towards each other under the cooperation of the first connecting rod 8, the second connecting rod 9 and the third connecting rod 12, thereby driving the wire trimming scissors 14 to move towards each other.

[0028] Furthermore, the lower surface of the third connecting rod 12 is hinged to the upper surface of the mounting block 5 through a pin. Linear array distributed tightening grooves 13 are formed on the opposite surfaces of the two tightening clamps 11, and the tightening grooves 13 clamp the wire end sleeve.

[0029] Furthermore, one end of the tightening groove 13 penetrates and extends to the lower surface of the tightening clamp 11, and the multiple tightening grooves 13 are linearly array distributed and gradually increase, which can effectively adapt to wire end sleeves of different specifications, with stronger adaptability. A wire trimming scissors 14 is fixedly connected to one side surface of the tightening clamp 11, and a second partition plate 15 is fixedly connected to the inner bottom wall of the housing 1.

[0030] Furthermore, a block-shaped battery 16 is movably sleeved on the inner wall of the housing 1. A cover plate 17 is hinged to the back surface of the housing 1 through a pin. After the block-shaped battery 16 runs out of power, the block-shaped battery 16 can be replaced. Open the cover plate 17, and the block-shaped battery 16 can be taken out. The fully charged block-shaped battery 16 is stuffed into the interior of the housing 1, and the cover plate 17 is covered. The cover plate 17 is provided with a clamping block, and a matching clamping groove is arranged on the front surface of the housing 1, so as to fix the cover plate 17, enabling the battery to maintain a good electrical connection with the servo motor 3. A switch button 18 is fixedly installed on the upper surface of the housing 1.

[0031] Through the setting of the servo motor, the staff no longer need to manually tighten the wire end sleeve, and they will not be overly fatigued after long-term operation, which improves work efficiency. Moreover, the setting of the wire trimming scissors enables the trimming and alignment of the wire harness end without using other tools, making it more convenient to use. Finally, the setting of multiple tightening grooves of different sizes can effectively adapt to wire end sleeves of different specifications, with stronger adaptability.

[0032] Working principle: Step 1, when tightening the wire end sleeve of a bicycle, first trim the end of the wire harness that needs to have the wire end sleeve tightened. Align the wire trimming scissors 14 with the end of the wire harness, press the switch button 18, and the servo motor 3 starts. The servo motor 3 drives the lead screw 4 to rotate. With the cooperation of the guide rod 7, the rotation of the lead screw 4 drives the moving block 6 to move. The movement of the moving block 6, with the cooperation of the first connecting rod 8, the second connecting rod 9, and the third connecting rod 12, drives the tightening pliers 11 to move towards each other, thereby driving the wire trimming scissors 14 to move towards each other, and thus trimming the end of the wire harness neatly.

[0033] Step 2, when the trimming of the wire harness end is completed, put the wire end sleeve onto the wire harness. According to the size of the wire end sleeve, select a suitable tightening groove 13 to align with the wire end sleeve, and make the tightening pliers 11 move towards each other according to the steps of Step 1, thereby pressing the wire end sleeve tightly. When the usage time is relatively long and the battery block 16 runs out of power, the battery block 16 can be replaced. Open the cover plate 17, and then the battery block 16 can be taken out. The fully charged battery block 16 is inserted into the housing 1, and the cover plate 17 is covered. The cover plate 17 is provided with a clamping block, and the front of the housing 1 is provided with a matching card slot, thereby fixing the cover plate 17 and enabling the battery to maintain a good electrical connection with the servo motor 3.

[0034] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
